hibernate.jdbc.time_zone = UTC被忽略

Question

使用设置为Spring框架5.0.2.RELEASE Spring Security 5.0.0.RELEASE Hibernate 5.2.11.Final

我按照spring boot和Vlad的链接来配置我的应用程序，如下所示

db.properties -

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://hostname:port/appname?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false
jdbc.username = xxx
jdbc.password = xxx
jdbc.minPoolSize = 5
jdbc.maxPoolSize = 20
jdbc.maxIdleTime = 30000
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
spring.jpa.properties.hibernate.jdbc.time_zone = UTC

HibernateConfig.java

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages="in.greenstack.ikon")
@PropertySource(value = { "classpath:/resources/db.properties" })
public class HibernateConfig {

    @Autowired
    private Environment environment;

    @Bean(name = "myDataSource")
    ....

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "in.greenstack.ikon.entity" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        properties.put("spring.jpa.properties.hibernate.jdbc.time_zone", 
                environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));
        return properties;        
   }

实体 -

@Entity
@Table(name = "PROJECT_MASTER")
public class Project {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private int id;

@Column(name = "NAME")
private String name;

@Column(name = "START_DATE")
private Date startDate;

@Column(name = "END_DATE")
private Date endDate;

@ManyToOne
@JoinColumn(name = "FINANCIAL_YEAR")
private FinancialYear financialYear;

表定义 -

    CREATE TABLE `PROJECT_MASTER` (
    `ID` int(11) NOT NULL AUTO_INCREMENT,
  `NAME` varchar(50) NOT NULL,
  `FINANCIAL_YEAR` varchar(20) DEFAULT NULL,
  `START_DATE` date DEFAULT NULL,
  `END_DATE` date DEFAULT NULL,

从上面的日志中可以看出，绑定参数是从客户端发送的正确值（2017年4月1日和2018年3月31日），但是在db中保存时仍然保存不正确的日期。

请提出我错过的建议。

Answer 1

试试这个（它对我有用）。 在spring boot主应用程序文件中写下面的代码片段。

@PostConstruct
public void started() {
    TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
}

资源

Answer 2

改变这个：

 properties.put("spring.jpa.properties.hibernate.jdbc.time_zone", 
                environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));

对此：

 properties.put("hibernate.jdbc.time_zone", 
            environment.getRequiredProperty("spring.jpa.properties.hibernate.jdbc.time_zone"));

Answer 3

我认为你应该将spring.jpa.properties.hibernate.jdbc.time_zone = UTC放在main/或test/ application.yml / application.properties中，而不是db.properties 。 而且，我认为.properties优先于.yml 。 如果我错了，请纠正我。

并且，此时区配置也受Timezone.getDefault()影响。

看到这篇文章： https ： //aboullaite.me/spring-boot-time-zone-configuration-using-hibernate/

而且，正如我测试的那样，我看到如果你想保存一个java.util.Date ，它本身没有时区信息（只在其Calendar属性中，这是真的），并且列定义没有时区信息的地方，此属性将影响保存到DB的值，但不会影响从DB检索行时的值; 后者只受Timezone.getDefault() 。 同时，如果设置Timezone.getDefault() ，则保存和检索的值都将是您想要的时区。

因此，如果在同一应用程序中保存并查询信息，则此属性可能不是操作Date值的最正确方法。 只需使用Timezone.setDefault(Timezone.getTimezone("XXX")) 。
